Sports drinks play a crucial role in hydration during exercise, especially for prolonged activities. They provide essential electrolytes, such as sodium and potassium, which help replenish lost minerals through sweat. Additionally, these drinks typically contain carbohydrates to provide a quick source of energy, enhancing performance and endurance. However, it's essential to choose sports drinks wisely; they should be consumed based on the duration and intensity of exercise, as the high sugar content in some brands can lead to excessive caloric intake if not balanced with activity level.
